This battery quick disconnect switch is extremely heavy compared to the plastic switches I have had before.My Pros:1) Solid metal build;2) Firm on and off switching, with a definite click you can hear and feel;3) Heavy duty terminals.My Cons:1) Some play in the switch handle, its not much but it wiggles which takes away from the solid build feel of the switch.Overall, it is a decent metal battery disconnect switch that is competitively priced compared with other plastic switches.
